Improved brick-machine



PHILIP H. KELLS, OF ADRIAN, MICHIGAN IMPROVED BRICK-MACHINE.

Specification forming part of Letters Patent No. 63,057, dated March 19,1867.

To all whom it may concern:

Be it known that I, PHILIP H. KELLS, of Adrian, in the county of Lenawee and State of Michigan, have invented a new and Improved -BrickMachine5 and I do hereby declare the following to beV a full, clear, and exact description of the same, sufficient to enable one skilled in the art to which the invention' appertains to make use of it, reference being had to the accompanying drawings, forming a part of the specification, and in which- Figure lis an elevation and partial section. Fig. 2 is a top view. Fig. 3 is a section through one of the pug-mills, looking downward, and showing the opening through which the clay passes to the mold. Fig. 4 is a vertical section through a portion of the lower part of one pug-mill, and showing the throat and the introduction of the clay to the mold.

The clay is ground in two pug-mills, and pressed into molds on opposite portions of the same side of a wheel rotating on a vertical axis. The mold-wheel is supported by carrier-wheels. The clay is pressed into the molds by the blades of the pug-mill and a contracting throat, and is out oif, forming the upper surface of the brick, by the passage of the mold under a cutter-board. The brick is raised and discharged from the mold by a follower, moved from below by the passage of its carrier-wheel up an inclined plane on the .bed` track.

In the drawings, A Ais a frame, having an annular mold-bed, B, which is supported by a central hub, C, and carrier-wheels D, as it rotates beneath the pug-mills AE E, which occupy positions at opposite portions of the upper side of the mold-bed. The motions of the various parts are derived from the main shaft F, whose bevel-pinions rotate the wheels H H I I, the former of which, by means of the pinions K K, rotate the mold-bed, and the latter the vertical shafts J J of the pug-mills E E.

The pug-mills are supplied with clay, which is ground and tempered therein by the radial blades which project from the axis, and which ultimately press it through the throat b into the molds c.

As the mold-bed rotates, the molds are brought under the wedge-shaped piece d, which packs the clay still more closely into the molds, the lower edge of the wedge d keeping back all the clay not in the molds, and smoothing the molded clay on its upper surface as it passes beneath. The pug-mills are supported upon bridge-pieces h h, which rest upon the central hub C and upon the vframe A. v The brick, having passed from beneath the pugmill, is ejected from the mold by the raising of the follower m, which forms the bottom of the mold. This is accomplished by causing the carrier n, which supports the follower, to rise on the incline p and thrust the follower up even with the surface of the moldfbed, when the brick is removed by the attendant.

Having described my invention, what I claim therein as new, and desire to secure by Let- P. H. KELLS.
